Specification of Letters Patent.

Application filed October 6, 1909. Serial No. 521,408.

To all whom'itmay concern:

Be it known that I, ROBERT BAIRD, a subject of the King of Great Britain, and resident of West Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Forming Cigarette- Wrappers, of which the following is a speci fication.

The present invention relates to machines for forming cigarette wrappers, and particularly for forming two-ply wrappers in the shape of open-mouthed flaring bags or receptacles into which the tobacco may be conveniently filled and the completed cigarette expeditiously made without the necessity of first rolling and then moistening the edge of a single-blank wrapper as is now the usual custom.

Generally stated, the machine embodies mechanisms for handling two websof paper; applying an adhesive along predetermined-lmes on one of said webs; bringing the webs into position so that the sheets will adhere along the lines of the adhesive; cutting the web into a plurality of two-ply wrappers; applying mouth-piece material to the previously formed wrapper to provide a non-sticking tip for the smoker; and finally delivering the wrappers in sheet form 3 after which they may be separated into individual units, and all with a minimum waste of stock.

Referring to the drawings forming part of this specification, andin which I have illustrated one embodiment of my invention, Figure 1 is a side elevation, partly in section, of a machine constructed in accordance with my invention. Fig. 2 is an enlarged detail view of the web cutting roll. Fig. 3 is a development of the circumferential surface of the rollshown in Fig. 2. Fi 4: is an enlarged detail view of the adhesive applying roll. Fig. 5 is a development of the circumferential surface of the roll shownin Fig. 4. Fig. 6ris a view in side elevation of the mouth-piece forming roll. Fig. 7 is a transverse sectional view on the dotted line, Fig. 6, looking in the direction of the arrow. Fig. 8 is a diagrammatic view of a portion of the web, showing the wrappers after they have been formed on the web and prior to their separation therefrom.

Referring to the drawin s by numerals, like numbers indicating 1i e parts of the several views, 2 denotes one of the side frames of the machine, of which there are two duplicates, which may be mounted upon any suitable base, and tied together in any suitable manner, as, for example, by transverse tie-rods 3. v

Mounted in suitable hearings on the side frames, are rolls of cigarette paper, the roll 4 being preferably mounted, as shown, in suitable supporting arms at one side of the machine, While the roll 5 is mounted on the other side in upwardly extending supporting arms, this arrangement being for the sake of close assemblage and convenience in handling the webs delivered from the respective rolls 4 and 5, although it will be understood that the manner of mounting such supply rolls is immaterial, and that they may be placed in any convenient or desirable position for feeding the web into the machine. The web of paper from the roll 4: (see Fig. 1), passes over a drag or tension bar 6 which insures proper feed of the web, and thence to a posltively driven roll 7 which is shown in detail in Figs. 4 and 5, and is preferably the drive roll of the train of mechanism, this positively driven roll having formed thereon ribs 8, which, as shown in the surface projection of the roller illustrated in F ig. 5, are of the form and outline of the complete article or wrapper, the form of'the ribs 8 in the present instance being that of flaring U-shape, to produce a bag-like receptacle having an enlarged filling mouth or orifice, and it will be observed that for economy of space these U-shaped" ribs 8 are placed in reversed relation to one another transversely of the web. Opposed to this roll 7 and geared therewith so as to bear a proper timed relationthereto, is a second roll 9, the surface of which has the same ribbed conformation as the roll 7, so that, as the two rolls 7 and 9 rotate, the opposing ribs will register and press against one another.

/ The web from the roll 4, as it'passes over the ribbed roll 7, is pressed against the ribs 8 on such roller by an adhesive aplplying roll 10 which receives a suitable a hesive from a pot roll 11 rotating in a suitable pot, as shown in Fig. 1, said roll 11 being rovided with the usual scraper or laying b ade 12, in order to regulate the take-up of the adhesive from the pot. The roller'lO will, it is obvious, apply lines of adhesiveto the web coming from the roll 4 at the points where the ribs 8 on the roller 7 make contact witlrthe roll it) aiuLthe web will thus be striped with adhesive along these predetermined lines. From the web roll 5 the second web of cigarette paper passes over a drag or tension bar 13 to the roll 9 and is pressure rolls the two-ply sheet passes to aseeond pair of rolls l5 and 16, one of which is n-ovided'with a pressure element 17 in order that they may bear against each other with a yielding pressure. The roll 15 constitutes a bed roll, while the .roller 16, shown in detail in Figs. 2 and 3, is provided with cutting blades 18 of the same form and outline as the pressure ribs 8 heretofore described, and the bed roll 15 and cutting roll ll are so timed and geared with relation to the pressure rolls as that they will out the two-ply web along the lines of adhesion between the two sheets thereof. .The cutting roll 16 is alsov provided with perforating points 19 so positioned as to perforate the mouth tip of the double walled wrapper, as clearly shown in Fig. 8, so that not only will the w upper or receptacle which is formed from the two-ply web be a convenlent one for receiving the tobacco but this month piece or tip will also provide atip closed against the escape of tobacco but open to the egress of smoke.

It will be observed that the succeeding sections of the two-ply web are cut by the rollers just described only along substantially longitudinal lines, and that the web is intact transversely, so that it will continue to feed and run through the machine, as

will be apparent from Fig. 8 of the draw- 1ngs. After leaving the cutting rolls 15 and 16 just described, the two-ply cut web passes to the mouth-piece forming rolls 20, which are identical so far as surface configuration is concerned, and which, as shown 1n Figs. 6 and 7, have radial projections 21 of suitable form, which projections bear against pot rolls 25% mounted in suitable pots and provided with the usual scraper blades to regulate the deposit on their surfaces. In

the present instance this mouth-piece form-' ing mechanism is shown as designed to apply a mouth-piece of paraflin or slmilar nonadhesive material to the tip of thewrapper; this mouth-piece section being indicated by shaded lines in Fig. 8', and this is accomplished by so timing the rolls 20, which are geared up with the preceding mechanisms so as to rotate in. proper relation thereto, as that the projections 21 will register on either side with the tip portion of the wrappers, which, as already explained, have been severed from the web longitudinally. The last mentioned mechanism will impregnate the wrapper tips or cover them with suit: able mouth-piece material so that a nonsticking tip is provided. From the mouthtip mechanism the web passes out of the machine and the two-ply cut wrappers may then be completed by severing the web transversely at suitable points, as along the dotted lines 23 of the sheet, (see Fig. 8).

It will be seen that by means of this machine two-ply bag-like wrappers may be rapidly and accurately produced, the several mechanisms, as will be obvious from Fig. 1, being so intergeared and disposed that they are timed and correlated so as to complete the chain of operations necessary to the production of the wrapper very expeditiously.

While I have shown a particular embodiment of my invention, and that the best now-known to me, it will be obvious that many changes may be made within the skill of the mechanician without departing from my invention, and as all such mechanical departures are obviously within the purview of my invention, I do not limit myself to any of the details of construction herein illustrated for the purpose of disclosing the invention, except so far as 1 maybe limited by the prior art to which this invention belongs.
